Roller bearing vibration measuring device

Abstract

The invention discloses a roller bearing vibration measuring device. The roller bearing vibration measuring device comprises a mandrel for mounting a measured bearing, a sensor and a radial loading mechanism, wherein the sensor is positioned above the mandrel; a measuring head of the sensor is in contact with the outer surface of the top of the measured bearing on the mandrel to form a contact C;the radial loading mechanism comprises a first radial loading assembly and a second radial loading assembly which are arranged below the mandrel respectively. The roller bearing vibration measuring device is reasonable in structure; the load used during measurement is the same as that borne by the bearing during actual use, so that a measurement error is reduced, and that vibration and noises of the bearing can meet the using requirements of a customer in the mounting and using processes is guaranteed.

Description

【Technical field】 [0001] The invention relates to the technical field of bearings, in particular to a vibration measuring device for roller bearings. 【Background technique】 [0002] Thrust spherical roller bearings can withstand heavy loads on the shaft and are suitable for relatively high speeds. Since the raceway is inclined relative to the bearing axis, the bearing can also bear radial load, but the radial load must be less than 55% of the axial load. Thrust self-aligning roller bearings are separable bearings, the rollers are spherical, and the raceway of the seat ring is spherical, which has self-aligning performance. Because the load action line forms a certain angle with the bearing line, this type of bearing can bear axial and radial loads at the same time, and can be used in extremely heavy load occasions, and the allowable speed is also high. Oil lubrication is generally used when used. In general use occasions, the maximum allowable inclination angle is 2 degree...
